NON-SKID DEVICE.

To all whom t may concern: a

l.le it known that I, ELMER A. HENsAL, a citizen of the United States, and a resident of Panora, in the county` of Guthrie and State of Iowa, have invented a certain newI and useful Non-Skid Device, ofjwhich the following is a specification.

rIhe object of my invention is to provide a non-skid of simple, durable and inexpensivel construction.

More particularly it is my object to provide a non-skid device comprising a seriesv of tread plates or members designed to fit over aV tire, and to provide means for suc-1 cessively flexibly connecting the tread mem- 1oers together, said tread members being sub-.

stantially wider .than the wheel.

A further object is to provide such a device which may be put on the car as *van attachment for furnishing a broader treadf. than .the wheel ordinarily has.

lVith these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of the device whereby the objects contemplated-are attained, as hereinafter more fullyset forth, pointed out in my claim and y illustrated in the accompanyingdrawings,v

in which:

Figure 1 shows a side elevation of a por-f4 tion of a wheel with a tire thereon equipped with a non-skidl device embodying my in-- vention.

Fig. 2 shows a transverse,- vertical, sec-,l tional view through the rim and tire with my non-skid device installed thereon.

Fig. 3 shows a side elevation of a portionl of a modified form of a non-skid device. l Fig. L shows a detail, perspective view of a portion of a non-skid device; and

Fig. 5 shows a sectional view through one of the bracket members.

In the accompanying drawings, I have used the reference numeral 10 to indicate generally the spoke of a wheel which has the felly 11, the rim 12 and the cushion tire 13.

In Figs. 1 and 2 I have shown one form of my invention and in Fig. 3 another form.

In the form of my invention illustrated in Figs. 1 and 2 I have shown a series of tread members 14 each extending transversely across the tread of the tire, and having on its inner surface a socket or recess 15V designed to fit over the t1re. l

Fixed to the inner surface of each tread .by means of bolts 21a and nuts'21b.

member 14 at the opposite ends thereof, are

brackets comprising metal plates 16 having .:of by lmeans of links 21 which are mounted on the spindles 2O and are held in position vTwo of the adjacent links 21 have later- .ally extending flanges 22 designed to receive a bolt 23 by which the series of links on one side of the wheel may be adj ustably fastened in a continuous annular member.

illus- It has been my purpose to provide essentially anon-skid device, and also a Vtraction device whereby a broad tread may be furnishedto a truck or motor vehicle for traveling in mud or sand or the like.

Itis sometimes desirable that the nonskid device be detached from the wheel and 4laid out iiat, forming a track over which the wheels may travel in getting out of a mud sions 19. The inner endsof the extensions 19a are provided with loops 24C. The loopsV 24- arevarranged so that their openings are adapted to receive a continuous cable 29.

The ends of each cable 29 are connected together by means of a turn-buckle 26. l

In the form of my invention shown in Fig. 3 I provide links 27 similar to the links 21, with the exception that each link 27 has at least at one end a longitudinally elongated opening 28. The successive links are mounted on the spindles 20, and it will be lelen that the links may slide on said spines. After the device has been loosely installed on the Wheel, the turn-buckle 26 is manipulated for tightening the cable 29 for holding the non-skid device in a proper circle. Ii it is desiredto remove the form of Y' invention shown in Fig. 3 from the Wheel, for the purpose of laying the non-skid device out flat in front of the Wheel for furnishing a suitable track over which the vehicle Wheels may travel in getting out of a mud hole or the like, the turn-buckles are uli-screwed, and on account of the use ofthe slots 2S the tread members 14' may be laid flat onthe ground asshoWn-in Fig. 3.

The advantages of' a structure such as that herein shown may be largely seen iromy the foregoing description.v Y Y Y Tlie'parts are of simple and durable construction. The non-skid device may be quickly and easily installed on Vor removed 'fromy the Wheel.

My ,device does not impose any excessive` Wear or friction on the tire.

The use of my device reduces skidding to a minimum, and also furnishes a broad tread for securing maximum traction. Some changes may be made in the construction and arrangement of the parts .of my nonskid device Without departingV from theressential features and purposes of my invention7 andit is my intention to cover by my claim any modified forms of structure or use of mechanical equivalents which may be reasonably included Within the scope of my claim.

I claim as my invention:

yIn a non-skid device, a series of tread Y members arranged successively circumferentially around the tread portion of'a tire, said Y tread members each having a recess vformed on their inner suriace,V the recess beingl40V designed. to receive the tread portion of the tire and thus prevent lateral movementof t the tread member relative to the tire, each of said tread members being provided -vvith spaced members arranged to extend radially '45 n inwardly on the opposite sides of atire,k said I spaced members each-having-loops formed on their inner ends, links for pivotally and ,K
